Abstract

Small-scale tests conducted directly in the field, rather than in controlled environments such as flumes and wave tanks, provide a more accurate representation of natural conditions that help to understand performance and challenges in the real world. The present work addresses a field experiment conducted to investigate the influence of barnacles on wind-wave forces on a submerged horizontal cylinder. The experiment was carried out in a reserved marine area at the Marine Energy Laboratory (MEL) of the University of Reggio Calabria. The experimental setup consists of iron frames anchored to the seabed and supporting two identical and aligned cylinders. One is smooth and treated against fouling, while the other is given an artificial roughness by printing barnacles on it. The hydrodynamic force coefficients of the Morison equation and the transverse equation were derived from the experimental kinematics and the forces measured by pressure sensors along the cylinder circumference. The main results show that the total wave forces on the rough cylinder increase compared to the smooth cylinder, and the hydrodynamic force coefficients are generally higher. These findings can serve as a benchmark for detailed numerical studies which, once validated by the results of the present field tests, can investigate other configurations more economically and efficiently.
风浪对光滑和粗糙水平水下圆柱体的作用力:现场试验
直接在现场进行的小规模测试,而不是在水槽和波浪罐等受控环境中进行的测试,可以更准确地反映自然条件,有助于了解现实世界中的性能和挑战。本文通过野外实验研究了藤壶对水下水平圆柱体风浪力的影响。该实验是在雷焦卡拉布里亚大学海洋能源实验室(MEL)的一个保留的海洋区域进行的。实验装置由固定在海床上的铁框架组成,并支撑两个相同且对齐的圆柱体。一种是光滑的,经过处理防止污垢,而另一种是通过在其上印刷藤壶而获得人工粗糙度。根据实验运动学和压力传感器沿圆柱体周长测得的力,推导出了莫里森方程和横向方程的水动力系数。结果表明:粗糙圆柱的总波浪力比光滑圆柱的总波浪力大,水动力系数普遍较高;这些发现可以作为详细数值研究的基准,一旦得到目前现场试验结果的证实,就可以更经济有效地研究其他配置。

期刊介绍: Coastal Engineering is an international medium for coastal engineers and scientists. Combining practical applications with modern technological and scientific approaches, such as mathematical and numerical modelling, laboratory and field observations and experiments, it publishes fundamental studies as well as case studies on the following aspects of coastal, harbour and offshore engineering: waves, currents and sediment transport; coastal, estuarine and offshore morphology; technical and functional design of coastal and harbour structures; morphological and environmental impact of coastal, harbour and offshore structures.
